(Component Data)
| Shelf Life (cool, dry place) Flash | Shelf Life (in a cool, dry place) | At least 12 months Base at 27 °C, Curing Agent at 27 °C |
| Recommended Substrate | — Steel; abrasive blast cleaning to ISO standard Sa2.5 | |
| Condition and Temperature | — SigmaZinc109 application temperature must not be below 5 °C |
— During application and curing, substrate temperature must be above 5 °C and at least 3 °C above dew point1 / 3
| Instructions for use | Mixing ratio by volume base : hardener = 75 : 25— Base and hardener mixing temperature must preferably be above 15 °C; otherwise thinner should be added to achieve application viscosity— Excess thinner will reduce sag resistance and slow curing— Thinner should be added after components are mixed |
